On a budget, aren’t we all? Still, you want to buy a few trendy fashions to usher in spring. Consider buying anything with stripes, preferably a blouse or knit top, these item’s cost less than perhaps a new pair of trousers or a new dress. Plus striped blouses and tops are classical, you will be able to wear them until they are worn out.
Today, the research paradigm in the field relies on a broader perspective that takes into account the complete system within which tobacco use and tobacco control interventions operate.1 ,2 Acknowledging the complex drivers of tobacco use and related diseases, tobacco control researchers have become increasingly interested in systems science methods.3 ,4One approach used in systems science research is mathematical modelling which, broadly conceived, illustrates and attempts to quantify how a system’s components are inter related and how outcomes of interest might be affected when a system undergoes change.3 In tobacco control research, such models have been used to understand the future scope of disease burden,5 7 the potential effects of policies and regulations,8 10 and the economic consequences of interventions.11 13 However, there is currently no resource that provides an overview or synthesis of how these modelling techniques have been developed and used in tobacco control. This gap limits the ability of researchers to learn from and improve on existing models. Moreover, modelling approaches have been heterogeneous in their methods and even though they attempt to predict similar types of outcomes (eg, lung cancer, quality adjusted life years), results have not been adequately synthesised, weakening their ability to contribute to the evidence base for regulatory policy decisions.
